To all whom it may concern.-

Beit known that I, CLARENCE Z. HUBBELL, a cltizen of the United States, residing in Chicago, in the county of Cook and State ofv Illinois, have invented a new and useful Improvement in Car Couplers and Buffers, of which the following is a specification.

My invention relates to car coupler and buffer in which a series of parallel draw-bars is attached to rotating angle arms and a transverse yoke ties the opposite angle-arms together. At the same time the buffer-head and coupling-hooks act together with each other and with the angle-arms and yoke.

The object of my invention is to provide a means for securing an equality of action between two parallel reciprocating draw-bars and buffers, and I attain this object by means of the mechanism herein described, and illustrated in the accompanying drawings, in whicl1 Figure 1 is a View of the under side of two Y cars in juxtaposition, showing the method of applying my device to a car. Fig. 2 is an elevation and vertical sectional view of one end of a car, showing my mechanism at top and bottom of the car. Fig. 3 is a one-halfl elevation view of the end of a car with my mechanism at top and bottom.

Similar letters and figures refer to similar parts throughout.

At a convenient point on the timbers l of a car l I make a T-piece l5, the 'hood or head piece of which is bolted to the timber l. In the Harige is drilled ahole, and through this hole is passed the yoke l0. This yoke 10 is made of any desired length, and at convenient pointson the yoke lO are made collars 16 and 16. The ends of the yoke l0 pass through ball-headsQ on the ends of the angle-arm 8, in which ball-head 9 the yoke lO is constructed to adapt itself to the socket in the ball-head 9, 'whereby free oscillating motion is allowed the yoke 10 in the ball-head 9. On the yoke l0, at convenient points, are placed spiral springs 1l 12 17, which are controlled by the collars 16, and by the joint action of the said springs l1 l2 17 the yoke l0 is kept at ornear anequipoise. To the yoke 10, byproper device to allow of free play, the ball-head 9 connects the angle-arm S. This angle-arm 8 is made of suitable metal, bent at right angles and pivoted in the angle to the timbers of the car. From the pivot radiate the arms 6 and 7. On the end of the arm 7 is the ball -head 9, described, and on the end of `the arm 6 is pivoted the Ydraw-bars 2 and 2', as the case may be. On the end of the draw-bar is a coupling-hook 13, held by a strap 14 to the car-timbers. At a suitable point on the draw-bar 2 2 is made a lug, and to the lug by suitable device is secured the buffer-rod 5 5 and the bufferplate 4 4L. v

Having thus described the'parts .of my invention, I now proceed to explain the mand ner of using the same. I put the parts all together, as indicated, so that the yoke'lO will be held centrally by the T-piece l5, and the springs 1l, 12,'and 17 will keep the yoke 10 in a uniform relation with the other parts. The ends of the yoke 10 play in the ball-heads 9, and the angle-arm 8 transmits motion from the draw-bars 2 or 2 through the yoke lO to the other draw-bar 2 or 2', as the case may be. When two cars are coupled together,the hooks 13 engage and the buffer plates 4 4 are brought together, and when the cars'are run on astraight track the yoke lO is at right angles relative to the draw-bars 2 2'. When the l.cars run on curved track, the inner drawbars are compressed longitudinally and the outer ones elongated, thereby securing by `means of the yoke 1Q an equal draft, as is apparent.

Being aware that couplers and buffers are not`a new invention, as such I do not lay claim to the broad principal of coupler and That I do claim, and desire to secure by Letters Patent, is-

l. In a car coupler and buffer, the combination ofia series of Imre-Hel draw-bars having buffers attached thereto provided with an arm, and a spring to keep the butter-plates extended, the said draw-bars being pivoted to an angle-arm, and a means for imparting reciprocity7 of motion to the opposite drawbar through a rod supported transversely to the long` axes of the said cars, allsubstantially as and for the Apurpose set forth.

2. In a car coupler and buffer, the combination of an oscillating yoke centrally supported and controlled by springs with an an- ICO glo-arm pivoted to the timbers of a eau', and izng the tension on the said draw-bays, all draw-bar uniting tWo oars, all substantially substantially its and for the pnrposee set 1o as and for the purpose set forth. forth.
